Wiseco Chevy Small Block 4.140in Bore 1.060in CH 12.00 CC Piston Set

If you're building a serious performance engine for your Chevy Small Block, Wiseco's Professional Series forged pistons are a solid choice. This set is designed for a 4.140-inch bore and features a 1.060-inch compression height, with a 12.00 CC dish volume. They're built from 2618 aluminum, which offers improved tensile strength for the demanding conditions of racing.

These pistons are fully machined in the USA and come with precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. They also include an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The crown is also fully machined, and the design incorporates forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. These are intended for heavy to severe duty race applications where durability and performance are critical.

This set includes eight pistons, rings, and wrist pins. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
